Detailed Description

Simple frequency domain band pass.

Date:

2001/12/07 14:03:51

Revision:

1.19

Thanks:

Thanks to C. Charles Law who developed this class.

This filter only works on an image after it has been converted to frequency domain by a vtkImageFFT filter. A vtkImageRFFT filter can be used to convert the output back into the spatial domain. vtkImageIdealLowPass just sets a portion of the image to zero. The result is an image with a lot of ringing. Input and Output must be floats. Dimensionality is set when the axes are set. Defaults to 2D on X and Y axes.

Member Function Documentation

vtkImageIdealLowPass* vtkImageIdealLowPass::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkImageToImageFilter.

virtual const char* vtkImageIdealLowPass::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageToImageFilter.

int vtkImageIdealLowPass::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageToImageFilter.

virtual int vtkImageIdealLowPass::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageToImageFilter.

vtkImageIdealLowPass* vtkImageIdealLowPass::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageToImageFilter.

void vtkImageIdealLowPass::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkImageToImageFilter.

virtual void vtkImageIdealLowPass::SetCutOff (  float   , float   , float    )  [virtual]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).

virtual void vtkImageIdealLowPass::SetCutOff (  float   [3] )  [virtual]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).

void vtkImageIdealLowPass::SetCutOff (  float    v )  [inline]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing). Definition at line 80 of file vtkImageIdealLowPass.h.

void vtkImageIdealLowPass::SetXCutOff (  float    v )

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).

void vtkImageIdealLowPass::SetYCutOff (  float    v )

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).

void vtkImageIdealLowPass::SetZCutOff (  float    v )

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).

virtual float* vtkImageIdealLowPass::GetCutOff (    )  [virtual]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).

virtual void vtkImageIdealLowPass::GetCutOff (  float &   , float &   , float &    )  [virtual]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).

virtual void vtkImageIdealLowPass::GetCutOff (  float   [3] )  [virtual]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).

float vtkImageIdealLowPass::GetXCutOff (    )  [inline]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing). Definition at line 85 of file vtkImageIdealLowPass.h.

float vtkImageIdealLowPass::GetYCutOff (    )  [inline]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing). Definition at line 86 of file vtkImageIdealLowPass.h.

float vtkImageIdealLowPass::GetZCutOff (    )  [inline]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing). Definition at line 87 of file vtkImageIdealLowPass.h.

void vtkImageIdealLowPass::ThreadedExecute (  vtkImageData *    inData, vtkImageData *    outData, int    outExt[6], int    id )  [protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method. Reimplemented from vtkImageToImageFilter.
